Description

Technical Field

[0001] The present invention relates to the technical field of vehicle charging and battery replacement, and in particular to a vehicle battery replacement method and a battery replacement station. Background Art

[0002] At present, the main ways for new energy vehicles to replenish energy are charging at charging piles and battery replacement at battery swap stations. Replacing the battery box directly at the battery swap station can greatly shorten the vehicle's energy replenishment time. Car owners do not need to wait for a long time and can quickly replace the battery and continue to drive on the road, effectively alleviating the range anxiety problem of insufficient charging piles for pure electric vehicles.

[0003] However, since the horizontally arranged battery boxes in the battery swap station need to be equipped with firefighting equipment, the intervals between adjacent battery boxes are large, and it takes a long distance to transport the battery boxes horizontally to the battery swap location, and the battery swap takes a long time. In a multi-story battery swap station, if there is a long-distance high-altitude movement, falling from a high altitude is more dangerous than falling from a low altitude, and there will be greater safety hazards.

[0051] In this embodiment, in a battery swap station with multiple layers of battery boxes 40, since the horizontally arranged battery boxes 40 need to be equipped with firefighting equipment 30, etc., the intervals between horizontally adjacent battery boxes 40 are relatively large, and a relatively long distance is required to transport the battery boxes 40 horizontally toward the battery swap position 50. If the battery boxes 40 need to be moved at high altitudes over long distances, the movement speed is relatively slow, and the battery boxes 40 falling from high altitudes are more dangerous than falling from low altitudes, which will not only affect the battery swap efficiency, but also pose a greater safety hazard. To this end, this embodiment discloses a vehicle battery swap method. Figure 1 As shown, the vehicle battery replacement method includes steps S10 to S60, and the above steps are described in detail below:

[0052] Step S10, based on the battery swap station being in working state, obtain the incoming vehicle information of the battery swap position 50 at a preset frequency. The incoming vehicle information may include the incoming vehicle status and the waiting status. In the incoming vehicle status, the vehicle is ready to replace the battery box 40. The battery swap station includes a battery swap base station 10, multiple charging seats 20 and multiple battery boxes 40. The battery swap base station 10 charges the battery box 40 through the charging seat 20. The charging seat 20 is distributed in a first area 60 and a second area 70. The horizontal distance from the first area 60 to the battery swap position 50 is less than the horizontal distance from the second area 70 to the battery swap position 50. The charging seat 20 is distributed in two layers vertically. Before each battery swap starts, the number of charging seats 20 is greater than the number of battery boxes 40 in the battery swap station to ensure that the battery boxes 40 removed from the vehicle have spare charging seats 20 for charging.

[0053] Step S20, based on the battery swap position 50 switching from a waiting state to an incoming vehicle state, the battery box 40 on the vehicle at the battery swap position 50 is removed and loaded onto the unloaded charging seat 20, and the vehicle switches to a power unloading state.

[0054] Step S30, based on the fact that the vehicle is in a power-discharging state, obtain the charge state of all battery boxes 40 in the first area 60 and the charge state of the battery boxes 40 in the lower layer of the second area 70. That is, determine whether the power of the battery boxes 40 in the first area 60 and the lower layer of the second area 70 meets the battery replacement needs of the vehicle. Since the upper layer of the second area 70 is far away and the battery boxes 40 are high, in order to avoid the battery boxes 40 moving long distances at high altitudes, the charge state of the battery boxes 40 in the lower layer of the second area 70 is obtained first. The charging seat 20 on the upper layer of the second area 70 keeps the battery boxes 40 that are not fully charged in a charging state for as long as possible, so the charging seats 20 on the upper and lower layers of the second area 70 have clear functional divisions.

[0055] Step S40, based on the fact that the number of fully charged battery boxes 40 in the first area 60 is 0, and the number of fully charged battery boxes 40 in the lower layer of the second area 70 is greater than 0, grab the fully charged battery boxes 40 and move them horizontally toward the battery exchange position 50. At this time, the fully charged battery boxes 40 in the lower layer of the second area 70 are pushed out and grabbed, and the battery boxes 40 can be quickly moved horizontally toward the battery exchange position 50 at low altitude, saving battery exchange time while preventing the battery boxes 40 from falling from high altitude.

[0056] Step S50, based on the fully charged battery box 40 moving horizontally to near the battery replacement position 50, the battery box 40 is controlled to rise. At this time, the distance moved by the battery box 40 at high altitude is shorter, and the risk of falling from high altitude is lower.

[0057] In step S60 , based on the fact that the fully charged battery box 40 and the charging position of the vehicle are at the same height, the fully charged battery box 40 is loaded to the charging position on the vehicle, and the vehicle is switched to the charging state.

[0058] The above method can ensure that when a vehicle replaces a battery box 40, the battery swap station will give priority to grabbing a fully charged battery box 40 at a long distance, so that the battery box 40 can be moved horizontally for a long distance at a low altitude as much as possible, thereby ensuring the efficiency and safety of battery swapping.

[0059] In this embodiment, step S20 may include:

[0060] Step S21, based on the battery swap position 50 switching from the waiting state to the incoming vehicle state, obtain the loading state of the charging seat 20 in the first area 60. The loading state includes full load and empty load. Full load means that the battery box 40 is charged in the charging seat 20.

[0061] Step S22, based on the fact that the number of unloaded charging seats 20 in the first area 60 is greater than 0, the battery box 40 on the vehicle at the battery swap position 50 is removed and loaded onto the unloaded charging seat 20, and the vehicle is switched to a power-unloading state.

[0062] Through the above method, the battery box 40 on the vehicle can be preferentially loaded onto the charging seat 20 in the first area 60 after being disassembled, reducing the moving distance of the battery box 40 after being disassembled, achieving the purpose of rapid disassembly, and then the fully charged battery box 40 in the first area 60 or the second area 70 can be grabbed and loaded into the charging position of the vehicle. Since the disassembly process is fast and will not affect the overall battery replacement time, the overall battery replacement time only depends on the time to grab the fully charged battery box 40, which is convenient for improving the battery replacement efficiency.

[0063] In this embodiment, step S30 may include:

[0064] Step S31 , based on the vehicle being in a power-discharging state, the charge states of all the battery boxes 40 in the first area 60 are acquired.

[0065] Step S32 , based on the fact that the number of fully charged battery boxes 40 in the first area 60 is greater than 0, the fully charged battery boxes 40 are grabbed and loaded into the charging position on the vehicle, and the vehicle is switched to the charging state.

[0066] Step S33 , based on the number of fully charged battery boxes 40 in the first area 60 being 0, the charge state of the battery boxes 40 in the lower layer of the second area 70 is obtained.

[0067] The above method enables the battery swap station to preferentially grab the fully charged battery boxes 40 in the first area 60, so that the battery boxes 40 removed from the vehicle and the installed battery boxes 40 are preferentially selected from the first area 60, thereby reducing the moving path when the battery boxes 40 are replaced and improving the battery swap efficiency. Only when there are no battery boxes 40 that meet the battery swap requirements of the vehicle in the first area 60, will the battery boxes 40 in the lower layer of the second area 70 be considered for replacement, thereby reducing the time it takes for the battery boxes 40 to move at high altitudes.

[0068] In this embodiment, the vehicle battery replacement method may further include:

[0069] Step S70, based on the vehicle being in a charging state or the battery swap position 50 switching from an incoming vehicle state to a waiting state, obtain the loading state of the charging seat 20 in the first area 60. When the battery swap position 50 is in a waiting state, the number of charging seats 20 is equal to the number of battery boxes 40 plus 1, so that only one unloaded charging seat 20 is always reserved before battery swapping, thereby improving the utilization rate of the charging seat 20 of the battery swap station.

[0070] In step S80 , based on the fact that the charging seats 20 in the first area 60 are all in a fully loaded state, the battery box 40 with the lowest state of charge in the first area 60 is adjusted to the unloaded charging seat 20 in the second area 70 .

[0071] Through the above method, the battery box 40 with the lowest state of charge (least power) in the first area 60 can be moved to the unloaded charging seat 20 in the second area 70 by taking advantage of the gap between when the previous vehicle has completed battery replacement and is preparing to leave and when the next vehicle has not arrived. This allows the disassembled battery box 40 to be quickly loaded in the first area 60 when the subsequent vehicle replaces its battery, thereby improving the efficiency of removing the battery box 40 from the vehicle.

[0072] In this embodiment, step S80 may include:

[0073] In step S81 , based on the fact that the charging seats 20 in the first area 60 are all in a fully loaded state, the charge state of the battery box 40 in the first area 60 and the position of the unloaded charging seats 20 in the second area 70 are obtained.

[0074] Step S82 , based on the fact that the unloaded charging seat 20 in the second area 70 is located at the upper layer, the battery box 40 with the lowest state of charge in the first area 60 is adjusted to the unloaded charging seat 20 in the second area 70 .

[0075] Through the above method, in the process of adjusting the charging position of the battery box 40, the battery box 40 with the least power in the first area 60 is preferentially loaded onto the unloaded charging seat 20 on the upper layer of the second area 70, so that the charging seat 20 on the upper layer of the second area 70 can be kept in a fully loaded state as much as possible, and the battery box 40 on the upper layer of the second area 70 is a low-power battery box 40 that has just arrived at the battery exchange base station 10. In this way, the charging seat 20 on the upper layer of the second area 70 can be kept in a charged state for a long time, reducing the number of times the battery box 40 is grabbed from the upper layer of the second area 70, so that the battery box 40 is grabbed from the lower layer of the second area 70 and moved directly horizontally at low altitude and quickly, avoiding the battery box 40 from being grabbed from the upper layer of the second area 70. The ultra-long path of first descending, then moving, and finally rising to be loaded onto the vehicle is avoided, thereby improving the battery exchange efficiency and avoiding the safety hazard of the battery box 40 moving long distances at high altitude.

[0076] In this embodiment, step S82 may include:

[0077] Step S821, based on the unloaded charging seat 20 in the second area 70 being located at the lower layer, the position of the charging seat 20 is adjusted until the unloaded charging seat 20 is located at the upper layer. At this time, the battery box 40 with the highest state of charge at the upper layer of the second area 70 can be loaded onto the charging seat 20 at the lower layer.

[0078] Step S822: Based on the fact that the unloaded charging seat 20 in the second area 70 is located on the upper layer, the battery box 40 with the lowest state of charge in the first area 60 is adjusted to the unloaded charging seat 20 in the second area 70. This ensures that the charging seat 20 in the first area 60 is in an unloaded state, and facilitates the rapid loading of the battery box 40 removed from the vehicle to the charging seat 20 in the first area 60 for charging, thereby improving the battery replacement efficiency.

[0079] Through the above method, it is ensured that the charging seat 20 on the upper layer of the second area 70 is always in a fully loaded state, reducing the number of times it is grabbed during the battery replacement process, and the battery box 40 in the first area 60 and the battery box 40 in the lower layer of the second area 70 are in a relatively good charge state, which can ensure that the battery box 40 can move horizontally at low altitude, avoiding the safety hazard of moving the battery box 40 for long distances at high altitude.

[0080] In this embodiment, the vehicle battery replacement method may further include:

[0081] Step S90, based on the fact that the number of unloaded charging seats 20 in the first area 60 is greater than 0 and the battery exchange position 50 is in a waiting state, adjust the unloaded charging seats 20 in the first area 60 to be located in the upper position of the first area 60.

[0082] like Figure 4As shown, the charging seats 20 are arranged in multiple rows along the first horizontal direction. The charging seats 20 are arranged in two rows along the second horizontal direction. The first horizontal direction is perpendicular to the second horizontal direction. There is a transfer channel 80 between the two rows of charging seats 20. In order to save the floor space of the battery swap station, the two lower rows of charging seats 20 can share the same transfer channel 80. Since the charging seats 20 are required to move the battery boxes 40 to the transfer channel 80 before grabbing the battery boxes 40 in the lower layer, when one of the lower rows of charging seats 20 extends to the transfer channel 80, it will block the battery boxes 40 in the other lower row that are arranged relatively. Through the above method, the battery boxes 40 in the first area 60 can be dispatched so that the unloaded charging seats 20 in the first area 60 are located in the upper layer of the first area 60. In the case where the unloaded charging station 20 is located at the lower layer of the first area 60, when the battery box 40 disassembled from the vehicle is loaded into the lower layer of the first area 60, due to the obstruction of the lower battery box 40 on the opposite side, when grabbing the fully charged battery box 40, it is inconvenient to grab even if the blocked battery box 40 is fully charged, resulting in a lack of an option to grab the fully charged battery box 40, which in turn affects the grabbing efficiency. After the unloaded charging station 20 is adjusted to the upper layer of the first area 60, this problem is effectively avoided in this embodiment, thereby improving the battery replacement efficiency.

[0083] In this embodiment, step S90 may include:

[0084] Step S91 , based on the fact that the number of unloaded charging seats 20 in the first area 60 is greater than 0, obtain the position information of the unloaded charging seats 20 in the first area 60 .

[0085] Step S92, based on the fact that the unloaded charging seat 20 in the first area 60 is located on the upper layer, the battery swap station is controlled to be in a standby state.

[0086] Step S93, based on the fact that the unloaded charging seat 20 in the first area 60 is located at the lower level and the battery exchange position 50 is in a waiting state, adjust the unloaded charging seat 20 to the upper level of the first area 60.

[0087] Through the above method, any battery box 40 on the upper layer of the first area 60 can be adjusted to the lower layer of the first area 60, so that the unloaded charging seat 20 in the first area 60 is located on the upper layer of the first area 60, thereby avoiding that the battery box 40 disassembled from the vehicle is loaded onto the charging seat 20 for charging and affecting the fully charged battery box 40 in the lower layer of the first area 60 being grabbed and loaded onto the vehicle, thereby improving the battery replacement efficiency.

[0088] In this embodiment, if Figure 2 , Figure 3 , Figure 5 , Figure 6 As shown, this embodiment discloses a battery swap station, which is applied to a vehicle battery swap method in any one of the above embodiments. Figure 4As shown, the battery swap station may include: a battery swap base station 10, multiple charging seats 20, multiple fire-fighting equipment 30, and multiple battery boxes 40. One side of the battery swap base station 10 is the battery swap position 50 for the vehicle. Multiple charging seats 20 are distributed in the first area 60 and the second area 70 of the battery swap station. The horizontal distance from the first area 60 to the battery swap position 50 is less than the horizontal distance from the second area 70 to the battery swap position 50. The charging seat 20 is distributed in two layers vertically, so that a large number of battery boxes 40 can be stored. The fire-fighting equipment 30 and the charging seat 20 are staggered. The fire-fighting equipment 30 corresponds to the charging seat 20 one by one. The fire-fighting equipment 30 is detachably connected to the charging seat 20. The battery swap base station 10 charges the battery box 40 through the charging seat 20. Before each battery swap begins, the number of charging seats 20 is greater than the number of battery boxes 40 in the battery swap station to ensure that the battery box 40 removed from the vehicle can be charged on the unloaded charging seat 20.

[0089] In other embodiments, the charging seat 20 located at the lower layer can drive the battery box 40 to slide horizontally so that the battery exchange station can avoid the battery box 40 on the upper layer when grabbing the battery box 40 on the lower layer, thereby improving the battery exchange efficiency.

[0090] In this embodiment, if Figure 4 As shown, the charging seats 20 are arranged in multiple rows along the first horizontal direction. The charging seats 20 are arranged in two rows along the second horizontal direction. The first horizontal direction and the second horizontal direction are perpendicular to each other. There is a transfer channel 80 between the two rows of charging seats 20. Through the above arrangement, the battery boxes 40 loaded on the two rows of charging seats 20 share a transfer channel 80, which can further store more battery boxes 40 and improve space utilization.

[0091] The charging seat 20 at the lower level is connected to the battery swap base station 10 by sliding along the second horizontal direction, so that the battery swap station can grab the battery box 40 at the lower level or load the battery box 40 to the charging seat 20 at the lower level.
